Opportunities for Urban Community Connectivity with CBRS, OSS, and NGOs
summary
A cooperative urban cellular system called Othello uses CBRS spectrum, printed SIMs and a distributed ledger to pre-generate authentication vectors on a ledger so thousands of micro-operators can authenticate and bill users without central roaming agreements. It runs Community LTE (colti) derived from OpenAirInterface, experiments with Magma orchestrator peering, and shows real performance—60 Mbps down 8 Mbps up at 2.1 km in dense terrain. Deployments operate on Tacoma roofs serving nearby families and partner organizations (Tacoma Cooperative Network, King County equity groups, Althea Networks, City of Seattle Internet for All).
